Summary

This study tests whether a gentle, targeted electrical stimulation to the brain (HD-tDCS) can safely improve how stroke survivors perceive vertical balance. Participants who have had a stroke affecting one side of the brain will receive either active or sham stimulation while performing visual tasks. The goal is to see if this approach can correct errors in judging what is upright, which may help with balance and daily activities.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: High-Definition transcranial Direct Current Stimulation (HD-tDCS)
What this could lead to: If it works, this could point toward a non-invasive treatment to improve balance and spatial awareness after stroke.
What could go wrong: This is an early-phase study with only 28 participants, so results may not apply broadly. The stimulation may cause mild discomfort or not improve perception.
